A noteworthy aspect of the BitTorrent Open Source Licence is that it does not grant trademark licence. The trademark "BitTorrent" is owned by the company BitTorrent Inc. and is governed by the Trademark Use Guidelines available here: http://www.bittorrent.com/trademark.html

Although the licence is derived from an OSI approved license, this licence has not been approved. Furthermore, the approved version of the Jabber licence is no longer used or recommended for use by its authors.[1]
